IIIF Downgrade

A basic library for converting IIIF v3 manifests to v2.

Why on earth would one do such a thing?

Certain applications (Spotlight until very recently) expect a v2 manifest. This lets someone easily take a v3 manifest from elsewhere and convert it to v2.

Warnings and Other Notes

This only handles the simplest of use cases like images or compound works of images. IIIF Presentation v2 has a much more limited set of applications than v3. This will likely create v2 manifests that are often invalid if you give it things it can't handle.

How to Use

As a library:

from iiif_downgrade import IIIFv3toV2Converter
import json

with open("fixtures/0e9016f7-f9dd-413f-b671-f75d181cbb5e.json") as f:
    data = json.load(f)

converter = IIIFv3toV2Converter(
    manifest=data,
    manifest_id="https://example.org/manifest/v2/123.json"
)

converter.convert()
converter.save("manifest-v2.json")

As a command line utility:

iiif_downgrade convert_directory -i fixtures

You can also find and replace ids and write to a specific directory:

iiif_downgrade convert_directory -i fixtures -o output --id_find "/manifest/" --id_replace "/v2_manifest/"
